ABSTRACT:
An ultrasonic transmission/reception apparatus which can image both a minute tissue around a bone part in an object and a minute tissue inside the bone, at a high resolution. The apparatus includes a system control unit which controls the synthesizers so that a first ultrasonic wave may be transmitted from one of the transmission elements while its frequency is being swept, and that a second ultrasonic wave may be transmitted from the other transmission element while its frequency is being swept with a predetermined difference frequency held relative to the frequency of the first ultrasonic wave, a signal processing unit which subjects the detection signal of the ultrasonic echo to predetermined signal processing, a signal processing unit which subjects the detection signal of the vibro-acoustic sound to predetermined signal processing, and a display-image arithmetic unit which generates B-mode image data based on the detection signals subjected to the signal processing. The detection signal may be subjected to pulse compression processing.
